Spring Boot simplifies the creation of self-contained, production-ready applications based on the Spring framework that can be executed with ease. By adopting a specific perspective on the Spring ecosystem and various external libraries, it allows developers to dive in with minimal hassle. Typically, applications built using Spring Boot require very little Spring-specific setup. It includes features designed for production, such as monitoring metrics, health assessments, and the ability to manage configurations externally. Additionally, it offers curated 'starter' dependencies that streamline the setup of your build environment. Whenever feasible, Spring Boot automatically configures both Spring and third-party libraries to enhance usability and efficiency. This approach not only saves time but also helps maintain best practices in application development.
